  • Patent number: 10144057
    Abstract: A method for manufacturing a forged steel roll comprises: casting, by the ESR method, a steel ingot which contains, by mass %, C: 0.3% or more, Si: 0.2% or more, Cr: 2.0-13.0% and Mo: 0.2% or more, and further contains Bi at 10-100 ppm by mass; and forging the steel ingot to manufacture the roll. According to this method, since freckle defects can be sealed near the center of the steel ingot, the roll can be stably used over a long period of time.

  • Publication number: 20180274684
    Abstract: A coupling member is provided that includes a filtration member provided in a fluid passage in a coupling body to divide the fluid passage into an upstream pre-filtration passage section and a downstream post-filtration passage section. The filtration member includes a cylindrical part extending in the direction of a longitudinal axis and having a filtration portion. The cylindrical part divides a downstream portion of the pre-filtration passage section and an upstream portion of the post-filtration passage section from each other in the radial direction of the cylindrical part. Further, the fluid passage has a dust collecting part extending in the direction of the longitudinal axis from the downstream portion to a position closer to a downstream opening than the filtration portion of the filtration member. The dust collecting part is closed at a downstream end thereof.

  • Cap
    Patent number: 9884551
    Abstract: A cap includes a main body attached to an end part of a charging port for fuel gas. The main body includes an elastic deformable portion for locking the main body to the end part when the main body is attached to the end part. The cap further includes a cover covering at least part of the elastic deformable portion and surrounding the main body. The elastic deformable portion at least partially elastically deforms when the main body is attached to the end part and when the main body is detached from the end part. The cover is a separate member from the main body. When the elastic deformable portion elastically deforms, the cover applies force to the elastic deformable portion in a direction opposite from the deforming direction.

  • Patent number: 9214086
    Abstract: A wireless communication device for vehicle-to-vehicle communication includes a vehicle positioning module that uses sensors and detects a current position and a direction of the vehicle. In a map matching, pre-calculated route information and road network information based on the current position are retrieved from map data and a current link of the vehicle is identified and a potential signal pattern is determined regarding a position of next intersection and the road network information based on the current position, the direction of the vehicle and the current link. Based on the potential signal pattern, radio characteristics including a level of intensity, a frequency, and a direction are assigned. A transmitter produces a radio signal of the radio characteristics carrying the current position, the speed and the direction of the vehicle. An antenna module converts the radio signal from the transmitter into radio waves and radiates the radio waves.

  • Patent number: 8921005
    Abstract: A uniform and dense resin coat is formed on a surface of a peripheral region of a fuel cell separator. However, the formed resin coat may contain defects (holes). With the present invention, however, any such defects in the resin coat are coated with a metal coat. That is, when depositing metal in complex ions on the fuel cell separator by an electrodeposition process, the metal is adhered not only to a power generation region but also to a portion where the surface (separator base material surface) is exposed by the defects of the resin coat, thereby forming the metal coat on the defects. Thus, it is possible to improve the corrosion resistance of the fuel cell separator as compared to the case that the surface of the separator base material is exposed at the portions of the defects of the resin coat.

  • Patent number: 8269640
    Abstract: One embodiment of the present invention discloses an odor-generating alarm apparatus that can ensure the reliability of a releasing operation and the odor dispersibility. In an odor-generating alarm apparatus, when abnormality information indicating occurrence of an abnormal state is supplied from a sensor for occurrence of an abnormal state, an initiator is operated by a circuit portion, and the initiator displaces a piston of a driving portion and displaces a spray can with respect to a casing and switches the spray can to a releasing state, thus releasing an odorous liquid filling the spray can in the form of fine particles.

  • Patent number: 7975822
    Abstract: Three external tooth wet friction materials are each composed of an external tooth plate and a lining adhered to one surface thereof along an entire circumference. Three internal tooth wet friction materials are each composed of an internal tooth plate and a lining adhered to one surface thereof along an entire circumference. Then, the three external tooth wet friction materials and the three internal tooth wet friction materials are disposed side by side so as to constitute a multi-plate frictional engagement apparatus. A thickness of the internal tooth plate is made thinner in view of its good heat discharge capability, and the thickness of the external tooth plate is made thicker by that much.
